3.6 Labelling Commands

3.6.1 Drawing and Selecting Character Sets

The drawing of characters is done with the LB command. When the LB command is
transmitted, the plotter enters labelling made and draws the string of characters that follow
the LB command. For example, if
LPRINT "LBABCDabcd";CHR$(3)
is sent, the plotter will draw "ABCDabcd" from the current pen location. [ETX] CHR$(3) in
the above statement is a label terminator which is appended to the character string to
release the plotter from labelling mode. If the label terminator is omitted, the next command
sent will be interpreted as a string of characters. The label terminator can be changed with
the DT command.
The character set to be used by the LB command is specified by the CS, SS, CA and SA
commands, which are listed in Appendix C " Character Set Table" .
The character codes for the characters that can be drawn are CHR$(33) to CHR$( 126).
Among the control characters that cannot be drawn, from CHR$(0) to CHR$(32), the follow
ing characters have special functions in labelling. The other control characters will be ig
nored.
[ETX]CHR$(3):
[BS]CHR$(8):
[ HT]CHR$(9):
[LF]CHR$(10):
[VT]CHR$( 11):
[CR]CHR$(13):
[SO]CHR$(14):
[SI]CHR$( 15):
Various settings can be selected for the characters that are to be drawn. These include the
size of character (SI, SR), the drawing direction (DI, DR) and the character slant (SL) among
others.
